设计任务

课程设计的主要任务是利用GIS公共平台提供的二次开发环境开发一套“台风GIS软件”，在遵循国家台风编码的基础上，实现台风的运动轨迹可视化,以及台风经过区域的经济损失评估。

1．获取台风的各个时刻的空间位置关系；

2．建立空间数据及属性数据库；

3．建立空间数据的查询系统；

4．实现空间分析的基本功能（包括缓冲区分析、叠加分析等）；

5．提交书面报告（数据库设计、软件设计流程和软件使用说明等）和台风GIS系统软件运行程序及原始程序代码等。

空间数据库设计与建库

地价信息表(tf_price)

台风路径(tf_name)

台风信息表(tf_geo)

台风登陆信息表(tf_loacl)

数据是中国天气网(台风)爬的

地图是自己数字化的!!!!!!

界面自己设计的

代码自己敲的,

不会的全百度的!!!!!
